Other celebrities, such as Jennifer Lopez, Hailee Steinfeld and Tiffany Haddish also headed out to the popular event.

Haddish had quite the plan for her night.

"One - take your pictures because you're going to be dancing and you'll mess your hair up. Then thing two, I walk around the room, scope the room, see who I want to party with," she said. "Then three, get a drink - first water, then alcohol. Vodka. Then dance, dance, dance, more water, more vodka, dance, dance, dance, talk to people, talk to people, talk to people, dance, dance, dance - more water, more vodka."
